Application tiled June 9, 1913.

To all w71 om 'it may concern Be it known that we, GUY E. DICK and ROBERT M. BioLER, citizens of the United States, residing at Chippewa Falls, in the county of Chippewa, State of lllisconsin, have invented a new and useful Explosive- Engine, of which the following is a specification.

rlhe present invention relates to improve ments in explosive engines, one object of the invention, being the provision of a valve structure in which the valve is so mounted as to dispense with the use of packing rings or other packing medium, the valve itself being a resilient normally expanding member, and mounted for oscillation, so that the same is properly operated to control the intake and exhaust of the engine.

A further object of the present invention, is the provision of a novel valve structure, the valve itself being composed of a split cylinder having a normal tendency to separate, said cylinder being insertible within a casing disposed adjacent the respective in` take and exhaust ports of the engine, such intake and exhaust ports being led into the head of the engine so as to reduce the compression and explosion space, thereby utilizing to the maximum, the power generated by the explosion of the compressed charge.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

ln the drawings Figure 1 is a transverse sectional view through the cylinder showing the valves in operable relation, the operating mechanism being shown in diagram. Fig. 2 is a side elevation of one cylinder of an engine showing the valve casing and manifold connection. Fig. 3 is an enlarged perspective view of one of the intake or eX- haust valves per se.

Referring to the drawings, the numeral 1 designates the cylinder of the engine, which is provided with the explosion chamber 2, having the intake port 3 and the exhaust port 4i, said ports being so disposed as to be in direct communication with the chamber and thus prevent any pocketing or Specification of Letters Patent.

dead space, and so trapping the explosive charge, as to cause the exertion of the maximum explosion power thereof upon the pisf ton 18.

llwo horizontally disposed cylindrical valve casings 5 and 6 are provided, each one being adjacent to its respective ports 3 and 4: and in communication therewith, and having formed through the outer wall the apertures 7 and 8 respectively, the purpose of which will presently appear. A water jacket 9 surrounds the cylinder 1 and also the valve casings 5 and 6, so that all parts of the engine subjected to friction and heat will be properly cooled.

rllhe valves 10 and 10, each one of which is constructed similarly, are mounted for oscillation in the respective casing 5 or 6, and as the construction of each valve is similar, the description of one will suflice for both. The valve 10, as clearly shown in Fig. 3, is composed of a cylinder, a portion at 11 of which is thicker than the diametrically opposed portion at 12, there being provided a longitudinal slot or port 13, which constitutes the port for alinement with the respective intake or exhaust port of the engine. The middle of the valve is so constructed and tensioned as to have a normal tension to expand and increase the size of the port 13,

and consequently resiliently engage the ad jacent wall of its casing 5 or 6, and thus pro` vide a tight lit to prevent the escape of gases due to the compression and exhaust stroke of the piston 13. These valves are disposed for oscillation in their casings 5 and 6, and each valve is provided with an arm 11; which projects through its respective slot or aperture 7 8, by means of which the saine is readily accessible as before stated for op-l eration.

ln order to properly operate the respective valves 10-10 in proper timed relation to admit of the introduction of the explosive charge withinthe chamber 2 and the exhaust of'the burnt gases therefrom, the reciprocatory rods 14e-14 are connected to the respective arms 11 of the two valves as clearly shown in Fig. 1, the lower ends being disposed upon the eccentrics 15-15 carried by the counter shafts 16-16 of the engine. Each counter shaft is operably connected to the crank shaft 17 and thus the power piston 18 will operate the counter shafts and in proper timed relation for the respective valves 10--10. 1n the present ncycle engine.

stance, the valves are constructed and arranged to provide a four-.cycle engine, `but it is apparent that the same may be so con- .structed and arranged as to produce a :two The rods 14-14 and eccen-y *trics 15-15 4are indicative of one .of many means whereby the'valves lO-lO may be operated.

What is claimed is:

An explosive engine, including a vpower cylinder having oppositely disposed intake and exhaust vports adjacent the hood thereof, two parallel .horizontally disposed cylindrical valve casings carried bythe cylinder, one to each port, each casing being Vopen at one end, two longitudinally lsplit normally eX- panding open ended crescent in cross section shaped valves, one to each casing linsertible through-the open end of the casing, a power piston, a crank shaft, means operably conlnecting the crank shaft to the valves, where- ;by the valves are oscillated'to cause the slits ln testimony that we claim the foregoing i as our own, vwe have vhereto aliixed our sig natures in kthe presence of two witnesses.
